CANDY-CREAM HEATER AND COOLER.

SPECIFICATION forming part of Letters Patent N 0. 470,822, dated March15, 1892. Application filed March 4, 1891. Serial No. 383,785- (Nomodel.)

To all whom it may concern.-

Be it known that l, HENRY HEIDE, a citizen of the United States, and aresident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Apparatus for Cooling Hot LiquidSugar, ofwhich the following is a specification.

This invention relates to an improved apparatus for cooling boiledliquid sugar that is to be used in the manufacture of cream-candy, sothat the change from the crystalline structure into a soft creamy masscan be accomplished in a quicker and more convenient manner. For thispurpose my improved cooling apparatus consists of a coolingreceptaclehaving a jacket extending around the same and a pipe-coil composed of aseries of horizontal pipe-sections arranged at different levels withinthe receptacle, said pipe-coil and jacket being connected with awatersupply pipe and with a common dischargep The invention consists,secondly, of the combination, with a cooling-receptacle having a jacketsurrounding the same, of a pipe-coil formed of a series of horizontalpipe-sections arranged at different levels within the receptacle, awater-supply pipe connected with the pipe-coil and jacket, steam-supplypipes connected with the water-supply pipe and jacket, stop-cocks forshutting off the water and steam supply pipes, and a commondischargepipe for the water or steam in the pipe coil and jacket.

In the accompanying drawings, Figure 1 represents a vertical centralsection of my improved apparatus for cooling hot liquidsugar'preparatory to making cream-candy from the same; and Fig. 2 isahorizontal section of the same on line 2 2, Fig. 1, showing a plan viewof the pipe-coil.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents an open receptacle in the shapeof a kettle, which is provided with a jacket A, that extends around thesame, with a bottom opening a, and with a discharge tube a, that isclosed by a hinged trap-door a having a fastening device a for tightlyclosing the discharge-tube a, so as to prevent any escape of sugar fromthe interior of the recep tacle A while it is exposed to the coolingaction in the same. In the interior of the receptacle A is arranged apipe-coil O, which is formed of a number of horizontal coil-sections 0,that are arranged at different levels below each other within thereceptacle, the upper end of the pipe-coil (3 being connected with awater-supply pipe D, which is connected by a branch pipe D with thebottom part of the jacket A. The water-supply pipes D D are providedwith stop-cocks cl d, so that the supply of cold water to the pipe-coilO and jacket A can be shut off whenever desired. The lower end of thepipe-coil O is connected by an upwardly-extending pipe 6 to adischarge-pipe E, which is connected by a branch pipe E with the upperpart of the jacket A, said branch pipe acting as an overflow-pipe forthe cooling-water supplied to the jacket. Asteam-supply pipe F, having astop-cock f, is connected with the water-supply pipe D at a pointbetween the coil 0 and the stop-cock 01, so that when the latter is shutoif steam can be supplied to the pipecoil 0. A branch steam-pipe F isconnected with the lower part of the jacket, the branch steam-pipe Fbeing also provided with a stopcockf for shutting off the supply ofsteam to the jacket. The jacket A is further provided at its upper partwith a small ventpipe g, having a stop-cock g for permitting the escapeof the air when the jacket is to be filled with water. The water forcooling is either supplied by means of a force-pump or from a tank onthe top of the building, into which the water is'pumped.

The branch supply-pipeDisprovided,preferably, with two smalldischarge-pipes 61 each having a stop-cock 02 which is opened whenevereither the steam and Water of condensation or the cooling-water is to bedischarged from the jacket. When the cooling-water is to be dischargedpreparatory to admitting steam for heating the receptacle A, the stopcock d and the stop-cock d of the water-exit pipe d are opened and thewater, which is generally well-water, drawn off to the sewer, while whenthe steam and water of condensation are to be discharged from the jacketthe stop-cock d and the stop-cock of the watereXit pipe 61 are openedand the contents of the jacket returned to the boiler, whilesimultaneously air is permitted to enter into the jacket, so as toprevent the formation of a vacuum in the same.

The sugar which is to be worked up into cream-sugar (fondant) isdissolved in a boiling-kettle and then heated to the boiling temperatureuntil a perfectly-clear solution is obtained. This hotliquid sugaristhentransferred to the cooling-receptacle A, in which it is cooled off bypermitting cold water from the water-supply pipes D D to pass throughthe pipe-coil O and the jacket A, said coolin g operation beingnecessary preparatory to the kneading or mixing operation by which theliquid sugar is changed into cream sugar. hen the reduction oftemperature of the liquid mass is accomplished,the latter is transferredby opening the trap-door a of the cooling-vessel into amixing-machine,located below the same (not shown in the drawings) andthere exposed to the usual kneading or mixing action, whereby thecrystallizing of the sugar is prevented and a white creamy massobtained, which is known as cream sugar (fondant) During the cooling ofthe liquid sugar in the receptacle A a layer of sugar is deposited onthe cooling-surfaces of the pipe-coil O and the walls of the receptacleA. To transfer the entire body of sugar from the cooling-receptacle tothe mixing-machine it is also necessary to remove the adhering body ofsugar thathas settled on the cooliug-surfaces,which, owing to the closeproximity of the coil-sec tions, cannot be accomplished by mechanicalmeans, but is best accomplished by the action of the heat. For doingthis quickly the supply of cold wateris interrupted byclosing thestop-cocks cl cl of the water-supply pipes D 1), while the stop-cocks fand f of the steamsupply pipes F F are opened, so that steam is suppliedto the pipe-coil C and the jacket A, whereby the entire apparatus isheated and the sugar that is deposited on the surfaces of the pipe-coiland wall of the receptacle is liquefied and runs into the mixingmachine, where it is mixed or kneaded until the proper consistencyrequired for cream-candy is obtained.

By the apparatus described the hard manual work heretofore required inworking up theliquid sugar on marble or metallic coolingslabs isdispensed with, while, furthermore, a large quantity of sugar can betreated at one time and changed into cream sugar in a quicker, easier,and more uniform manner than by the manual treatment heretofore in use.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with a receptacle having a jacketsurrounding the same, of a pipecoil formed of a number of horizontalcoil-sections arranged at different levels within the receptacle, awater-supply pipe connected with one end of the coil and with the bottomof the jacket, independent stop-cocks in said supply-pipe for shuttingoff the supply of water to the pipe-coil and jacket, steamsupply pipesprovided with stop-cocks and connected with the pipe-coil and thejacket, and a common discharge-pipe connected to the other end of thecoil and the upper part of the jacket, so as to discharge the water orsteam, the construction being such that water and steam can bealternately supplied to said coil and jacket, substantially as setforth.

2. The combination, with areceptacle having a jacket surrounding thesame, of a pipecoil formed of a number of horizontal coil-sectionsarranged at different levels within the receptacle, a water-supply pipeconnected with one end of the pipe-coil and with thebottom of thejacket, independent stop-cocks in said supply-pipe for shutting off thesupply of water to the coil and jacket, drain-pipes connected with thewater-supply pipe for the jacket and provided with stop-cocks,steamsupply pipes provided with stop-cocks and connected with thepipe-coil and the jacket, and a common discharge-pipe connected to theother end of the coil and the upper part of the jacket, the constructionbeing such that 9 water and steam can be alternately supplied to saidcoil and jacket, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

HENRY IIEIDE.
